Abstract
Description
- The present disclosure relates generally to the application of fluids and, in particular, to a tool for use in applying a fluid onto a number of surfaces. Still more particularly, the present disclosure relates to a tool that can be attached to a robotic end effector for use in applying a fluid onto a number of surfaces with a desired level of precision.
- Some manufacturing and assembly operations may require that a high-viscosity fluid be applied onto various objects. As one illustrative example, certain assembly operations may require that a coat of sealant material be applied over the exposed ends of installed fasteners. The coat of sealant material may need to be applied in a manner that completely covers the exposed ends of the fasteners and the surfaces around the fastener.
- Oftentimes, manual tools are used to apply high-viscosity fluids, such as, for example, but not limited to, sealant materials, onto surfaces. An example of one of these tools is a brush that has a handle with bristles that are attached to the handle.
- For example, without limitation, a brush may be used to brush a coat of sealant material over an exposed end of a fastener element installed in an object and over a portion of the surface of the object surrounding the exposed end of the fastener element. A human operator, such as a qualified sealer, may dip the bristles of the brush into a container of sealant material and then use the bristles to brush the sealant material over the fastener element.
- When sealant material is to be applied over hundreds of fasteners, the human operator may need to frequently re-dip the bristles of the brush into the container of sealant material. This type of manual application of sealant material may be more time-consuming and require more effort than desired.
- Further, applying sealant material with precision using the process described above may be more difficult than desired. For example, when using a brush to apply sealant material over a fastener that has been installed in an object, ensuring that the sealant material completely covers all sides of the exposed end of the fastener as well as the surface around the fastener may require many more brush strokes than desired. In some cases, the brush may need to be angled relative to the fastener to cover all sides of the fastener with the sealant material.
- This type of manual application of sealant material may be more tiring for the human operator than desired. Therefore, it would be desirable to have a method and apparatus that take into account at least some of the issues discussed above, as well as other possible issues.
- In one illustrative example, an apparatus may comprises a base having a number of channels, a number of flexible members extending from the base, and an applicator extending from the base on a same side as the number of flexible members. A flexible member in the number of flexible members may have a fluid channel connected to at least one of the number of channels in the base to allow a fluid flowing through the number of channels to flow out of the fluid channel. The applicator may be configured to apply the fluid flowing out of the number of flexible members onto a number of surfaces.
- In another illustrative embodiment, a tool may comprise a base having a number of channels, a number of flexible members extending from the base, and a plurality of bristles extending from the base on a same side as the number of flexible members. A flexible member in the number of flexible members may have a fluid channel connected to at least one of the number of channels in the base to allow a fluid flowing through the number of channels to flow out of the fluid channel. The plurality of bristles may be configured to apply the fluid flowing out of the number of flexible members onto a number of surfaces. Lengths of bristles in the plurality of bristles and angles of the bristles in the plurality of bristles relative to the base may be varied such that the fluid may be applied onto the number of surfaces by ends of the plurality of bristles.
- In yet another illustrative embodiment, a method for applying a fluid onto a number of surfaces is provided. The fluid may be received within a number of fluid channels of a number of flexible members extending from a base. The fluid may be moved out of the number of fluid channels. The fluid may be applied onto the number of surfaces using an applicator extending from the base on a same side as the number of flexible members.
- In still another illustrative embodiment, a method for applying a fluid onto a number of surfaces is provided. The fluid may be dispensed from an exit of a dispensing device into a channel of a connector extending from a base of a tool. The fluid from the channel may be moved into a number of channels in the base. The fluid may be moved from the number of channels in the base into a number of fluid channels of a number of flexible members extending from the base of the tool on a side of the base opposite the connector. The fluid may be moved out of the number of fluid channels. The fluid may be applied onto the number of surfaces using a plurality of bristles extending from the base on a same side as the number of flexible members. Lengths of bristles in the plurality of bristles and angles of the bristles in the plurality of bristles relative to the base may be varied such that the fluid may be applied onto the number of surfaces by ends of the plurality of bristles.
- In summary, according to one aspect of the invention there is provided an apparatus including a base having a number of channels; a number of flexible members extending from the base in which a flexible member in the number of flexible members has a fluid channel connected to at least one of the number of channels in the base to allow a fluid flowing through the number of channels to flow out of the fluid channel; and an applicator extending from the base on a same side as the number of flexible members and configured to apply the fluid flowing out of the number of flexible members onto a number of surfaces.

In this illustrative example, fluid 104 may haveviscosity 112 greater than selectedthreshold 113. Selectedthreshold 113 may be, for example, without limitation, about 500 centipoise. -
Fluid 104 may be dispensed totool 102 fromend effector 114.End effector 114 may be a device or system configured for attachment to, for example, without limitation, a robotic device. The robotic device may be a robotic arm in some cases. In this manner,end effector 114 may be referred to as a robotic end effector. - In this illustrative example,

Dispensing device 117 may receive fluid 104 fromfluid source 116.Dispensing device 117 may be configured to dispense fluid 104 out ofexit 120 of dispensingdevice 117. In one illustrative example, dispensingdevice 117 may includenozzle 119 havingexit 120.Exit 120 may be an opening innozzle 119 through whichfluid 104leaves dispensing device 117. In other illustrative examples, dispensingdevice 117 may include a valve system for controlling the flow offluid 104 out of dispensingdevice 117 totool 102. - In this illustrative example,
tool 102 may includebase 122,applicator 124, number offlexible members 126, andconnector 128.Base 122 may havefirst side 123 andsecond side 125.First side 123 andsecond side 125 may be opposite sides ofbase 122. Further,base 122 may have number ofchannels 130 that extend fromfirst side 123 tosecond side 125.Connector 128 may be associated withbase 122 atfirst side 123 ofbase 122. As used herein, when one component is "associated" with another component, the association is a physical association in the depicted examples. - For example, without limitation, a first component, such as
connector 128, may be considered to be associated with a second component, such asbase 122, by being secured to the second component, bonded to the second component, mounted to the second component, welded to the second component, fastened to the second component, and/or connected to the second component in some other suitable manner. The first component also may be connected to the second component using a third component. Further, the first component may be considered to be associated with the second component by being formed as part of and/or as an extension of the second component. -

As depicted,connector 128 may havechannel 132.Connector 128 may be connected to dispensingdevice 117 offluid dispensing system 115 in a manner such thatfluid 104 flowing out ofexit 120 of dispensingdevice 117 flows intochannel 132 ofconnector 128. In this manner,connector 128 may be attached tofluid dispensing system 115 to fluidly connect dispensingdevice 117 toconnector 128. As a result,exit 120 of dispensingdevice 117 may be fluidly connected to channel 132 ofconnector 128. - Further,
connector 128 may be associated withfirst side 123 ofbase 122 such thatconnector 128 is fluidly connected tobase 122. In particular, fluid 104 flowing throughchannel 132 ofconnector 128 may flow into number ofchannels 130 ofbase 122.Channel 132 ofconnector 128 may be fluidly connected to number ofchannels 130 ofbase 122. -

As used herein, a "flexible member," such as one of number offlexible members 126 may be a structure comprised of any number of materials that allow the structure to have some flexibility. -
Flexible member 134 is an example of one of number offlexible members 126.Flexible member 134 may take the form offlexible tube 136 in one illustrative example.First end 135 offlexible member 134 may be associated withsecond side 125 ofbase 122, whilesecond end 137 offlexible member 134 may be exposed and located some distance away frombase 122. In this illustrative example,second end 137 may be an open end. - For example, without limitation,
flexible member 134 may be a hollow member havingfluid channel 138 that extends fromfirst end 135 tosecond end 137.Fluid channel 138 may be connected to at least one of number ofchannels 130 ofbase 122 to allow fluid 104 flowing through number ofchannels 130 to flow throughfluid channel 138 and out offluid channel 138 atsecond end 137.Fluid channel 138 may be fluidly connected to at least one of number ofchannels 130. In this illustrative example,second end 137 offluid channel 138 may not extend past the furthest tip ofapplicator 124. -
Applicator 124 may be used to apply fluid 104 that flows out offluid channel 138 onto at least one of number ofsurfaces 106. Further,applicator 124 may be used to apply fluid 104 that flows out of the fluid channel of each of number offlexible members 126 onto number ofsurfaces 106. - In particular,
applicator 124 may be moved over number ofsurfaces 106 in a manner that transfers at least a portion offluid 104 flowing out of number offlexible members 126 onto number ofsurfaces 106. For example, without limitation,tool 102 may be rotated such thatapplicator 124 is rotated over number ofsurfaces 106. In another example,applicator 124 may be moved in a sweeping motion over number ofsurfaces 106. -
Applicator 124 may be implemented in a number of different ways. For example, without limitation,applicator 124 may comprise at least one of number ofbrushes 140, number ofsponges 141, plurality ofbristles 142, plurality ofwires 143, plurality offilaments 144, or some other type of element or group of elements configured for use in applyingfluid 104 onto a surface. - In one illustrative example,
applicator 124 may comprise plurality ofbristles 142. In some illustrative examples, at least a portion of plurality ofbristles 142 may be angled relative to base 122 at an angle different from other bristles in plurality ofbristles 142. By angling the bristles in plurality ofbristles 142 at different angles, plurality ofbristles 142 may be able to apply fluid 104 onto surfaces having various shapes and/or geometries. - In another illustrative example, plurality of
bristles 142 may include first set ofbristles 146 and second set ofbristles 148. First set ofbristles 146 may be configured to extend tofirst position 150 located a first distance away frombase 122. Second set ofbristles 148 may be configured to extend tosecond position 152 located a second distance away frombase 122.First position 150 may be different frombase 122. In this manner, first set ofbristles 146 may be used to apply fluid 104 onto two different types of surfaces at the same time. - In yet another illustrative example, plurality of
bristles 142 may include first set ofbristles 146, second set ofbristles 148, and third set ofbristles 154. First set ofbristles 146, second set ofbristles 148, and third set ofbristles 154 may be configured to apply fluid 104 onto a first surface, a second surface, and a third surface, respectively, in number ofsurfaces 106. - In one illustrative example, first set of
bristles 146, second set ofbristles 148, and third set ofbristles 154 may extend frombase 122 atfirst angle 147,second angle 149, andthird angle 155, respectively.First angle 147,second angle 149, andthird angle 155 may all be different angles in this illustrative example. Further,first angle 147,second angle 149, andthird angle 155 may be selected for first set ofbristles 146, second set ofbristles 148, and third set ofbristles 154, respectively, based on the particular surface with which the set of bristles is to be used. - For example, without limitation,
first angle 147 for first set ofbristles 146 may be selected such that the ends, or tips, of first set ofbristles 146 contact a particular surface rather than the sides of first set ofbristles 146. In this manner, fluid 104 may be applied to this surface evenly and adequately. - When the sides of plurality of
bristles 142 touch a surface as opposed to ends 153 of plurality ofbristles 142, good agitation of plurality ofbristles 142 and coverage by plurality ofbristles 142 may not be achieved.Ends 153 of plurality ofbristles 142 may also be referred to as the tips of plurality ofbristles 142. Consequently, first set ofbristles 146, second set ofbristles 148, and third set ofbristles 154 may be angled relative to base 122 based on the surfaces to be contacted by these sets of bristles. - Further, the lengths of the bristles in plurality of
bristles 142 may be varied based on the angles of the bristles in plurality ofbristles 142 relative to base 122 to ensure that ends 153 of plurality ofbristles 142 contact number ofsurfaces 106. In particular, the lengths of plurality ofbristles 142 and the angles of plurality ofbristles 142 relative to base 122 may be varied such thatfluid 104 is applied onto number ofsurfaces 106 byends 153 of plurality ofbristles 142. - The illustration of
manufacturing environment 100 andtool 102 inFigure 1 is not meant to imply physical or architectural limitations to the manner in which an illustrative embodiment may be implemented. Other components in addition to or in place of the ones illustrated may be used. Some components may be optional. Also, the blocks are presented to illustrate some functional components. One or more of these blocks may be combined, divided, or combined and divided into different blocks when implemented in an illustrative embodiment. - In some illustrative examples, each bristle in plurality of
bristles 142 may extend frombase 122 at a different angle relative to the other bristles in plurality ofbristles 142. In this manner, different types of surfaces may be evenly and adequately coated withfluid 104 using plurality ofbristles 142. - With reference now to

bristles 211 may include bristles that are angled at different angles relative tobase 202. For example, bristle 212, bristle 214, and bristle 216 may all be angled at different angles relative tobase 202. Plurality ofbristles 211 may be angled relative to base 202 such that the exposed ends, or tips, of plurality ofbristles 211 may contact the surfaces selected for fluid application rather than the sides of plurality ofbristles 211. - As depicted, plurality of
bristles 211 may include bristles of varying lengths. The varying lengths of the bristles in plurality ofbristles 211 and the varying angles of the bristles in plurality ofbristles 211 relative to base 202 may ensure that fluid is applied evenly and with adequate coverage over selected surfaces. - In this illustrative example,
